High idle adjustment: screw, sensor and?
My idi doesn't seem to show any difference in cold and warm idling.
I tried the screw, but it doesn't change the idle. Is there something else that I need to be looking at?

Does the solenoid plunger move when you first turn the key to RUN when the engine's cold?
Are you pressing the pedal before starting the engine, to allow the solenoid plunger to move its full travel?

there is a temp sensor in the head near the side of the thermostat housing. you can only see it by looking straight down between the rad hose and alternator. if the plug is off the sensor, you will have no timing advance or cold idle increase.
